There is a lot of corrosion on the hose fittings and I can imagine what it would be like to start trying to break them loose to replace, especially with no indication of leakage. I know there is an age date on the hoses life not unlike our tires, just wondering. Talking with Foretravel here today and local Napa , I will take current receiver/dryer into their shops for a look see. I don't want to put exact same dryer in , in case it was the cause of the compressor failure. Both locations mentioned that the quantity of the desicant was the critical concern.
Country Coach used barrier hose that is compatible with 134a, but Prevost, for the dash a/c system, DID NOT until they switched over at the last minute when the government mandated it. If the system was converted, were the Prevost hoses to the dash a/c replaced with barrier hose? If this was not done, the system will continually be a leak problem from the Prevost hoses.
